Thermodynamics and Superradiant Phase Transitions in a three-level Dicke Model
Mathias Hayn, Tobias Brandes
We analyse the thermodynamic properties of a generalised Dicke model, i.e. a collection of three-level systems interacting with two bosonic modes. We show that at finite temperatur…

Superradiant phase transition in a model of three-level-lambda systems interacting with two bosonic modes
Mathias Hayn, Clive Emary, Tobias Brandes
We consider an ensemble of three-level particles in lambda-configuration interacting with two bosonic modes. The Hamiltonian has the form of a generalized Dicke-model. We show that…

Phase transitions and dark-state physics in two-color superradiance
Mathias Hayn, Clive Emary, Tobias Brandes
We theoretically study an extension of the Dicke model, where the single-particle Hamiltonian has three energy levels in Lambda-configuration, i.e. the excited state is coupled to…
